    How To Install Python 3.7 on CentOS/RHEL 7 & Fedora 34/33

    By 2 Mins Read

    Python is a powerful programming language. It is very friendly and easy to learn. At the writing time of this article Python 3.7.11 (in Python 3.7 series) latest stable version is available to download and install. This tutorial will help you to install Python 3.7.11 on your CentOS, Red Hat & Fedora operating systems.

    Step 1 – Requirements

    This Python installation required the GCC compiler on your system. Login to your server using ssh or shell access. Now, use the following command to install prerequisites for Python before installing it.

    yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel xz-devel

    Step 2 – Download Python 3.7

    Download Python using the following command from the Python official site. You can also download the latest version in place of specified below.

    cd /usr/src  
wget https://www.python.org/ftp/python/3.7.11/Python-3.7.11.tgz

    Now extract the downloaded package.

    tar xzf Python-3.7.11.tgz

    Step 3 – Install Python 3.7

    Use below set of commands to compile Python source code on your system using altinstall.

    cd Python-3.7.11 
./configure --enable-optimizations 
make altinstall

    make altinstall is used to prevent replacing the default python binary file /usr/bin/python.

    Now remove downloaded source archive file from your system

    rm /usr/src/Python-3.7.11.tgz

    Step 4 – Check Python Version

    Check the latest version installed of python. Use command python3.7 instead of just python.

    python3.7 -V 

Python 3.7.11

    Share.

      Hi everyone!
      You MUST install the ‘xz-devel’ package for centos 7 before ./configure and make. This must be the sequence:

      yum install gcc openssl-devel bzip2-devel libffi-devel zlib-devel
      yum install xz-devel
      ./configure –enable-optimizations
      make altinstall

      Otherwise the installation would be incomplete.

      PLEASE ADD THIS TO THIS TUTORIAL!!!

        no u can’t, u need to internet to download the required files. But, if you don’t have any access to the internet you could ask your friend to download the required files then you can copy it into your machine and install it there.

      From my system it was missing zlib for the make to work. I had to additionally install this as a prerequisite

      yum install zlib-devel

      Hi Rahul,

      Installed Python 3.7.7 using the steps in this article on RHEL 7.7
      python3.7 command is available after adding PYTHONHOME to path.
      I am unable to find command pip3.7 or pip3 or similar.
      Could you verify if pip is installed with this method Or do I have to install pip Or is there any additional config needed for pip3/3.7 command.

      HI Rahul,

      We do already have Py3.6.5 which was installed through Anancond. Now we need Py3.7.1 so I’ve installed Py3.7.1 using the above steps . It seems like it got installed by python3 -V still showing 3.6.5 only, not 3.7.1.

      Can you help?

      Succesfully Installed 3.7, but when i check version it is showing 2.7
      I tried python3 -V, but it is showing ” python3: command not found”.

      Below are the message after completing altinstall
      “setuptools in /usr/local/lib/python3.7/site-packages (40.8.0)”
      ” pip in /usr/local/lib/python3.7/site-packages (19.0.3)”.

      What else i need to do to make python3 as default.

      hi,

      Just a tip for those who will encounter the same problem i had here on “make altinstall” line.
      “zipimport.zipimporterror can’t decompress data zlib not available”, you just have to install zlib-devel
      (:~$ sudo yum install zlib-devel)
      then run again the make altinstall command

      by the way Thank you very much for this article Sir Rahul!

      Thankyou for such a thoughtful setup, cleaning up tar files , non destructive alinstall, such a breath of fresh air compared to most articles these days that assume so much about your environment.

      Thanks for the article, however under Centos 7 I got the following error:
      pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

      libssl-dev has been already installed:
      Package 1:openssl-devel-1.0.2k-16.el7_6.1.x86_64 already installed and latest version

      hi，
      I have a question.When I “make altbinstall”,
      I can’t create the common file “/usr/local/bin/python3.7m”，because of the
      limited authority，so recipe for target “altinstall” failed.What should I do next?
      thank you very much.(Sorry,my English is poor,can you understand what I say?)

      I have tried the suggestion to do the “sudo yum install libffi-devel” but that did not make any difference.

      Any suggestions to get past this error?

      thank you

      Instalou sem erros, porem quando procuro na pasta bin junto com as outras versões não aparece.
      E quando coloco python3.7 –version mostra como não instalado.
